NASA confirms that the James Webb Space Telescope has identified carbon dioxide on the Jovian moon Europa. The carbon dioxide, detected in a specific region on the moon's icy surface is believed to have originated from within its subsurface ocean.

The European Council broadly agrees on several measures to combat climate change. Among them is a ban on combustion engines for new cars beginning in 2035, setting aside €59 billion for a special fund to reduce the cost of transition for the poorest populations, to be paid out from 2027 to 2032, reduction of carbon dioxide emissions by 55% from the 1990 reference level, and a carbon market reform. Negotiations on the final version of these reforms is underway.

A recent paper in the journal "Nature" reports that although the 2019–20 Australian brushfires produced 700 million tonnes of carbon dioxide, they also resulted in a massive phytoplankton bloom larger in size than all of Australia that absorbed carbon dioxide as part of the photosynthesis process. The smoke also deposited approximately three times the amount of iron normally found in the ocean.

The Copernicus Atmosphere Monitoring Service reports that the Arctic Circle has experienced its worst wildfire season on record after the service released data indicating that a series of wildfires occurring in the first half of 2020, mostly in the Russian republic of Sakha, have emitted more than 244 million tons of carbon dioxide. The emissions within that period have increased by more than a third of carbon emissions in the whole of 2019.

The world's first commercial hydrogen-powered passenger train enters service in Lower Saxony, Germany. The Alstom developed train uses a hydrogen fuel cell which emits no carbon dioxide.

Concentrations of carbon dioxide ({{CO2}}) in the Earth's atmosphere surged by a record amount in 2016, according to the World Meteorological Organization.

While attempting to create a nanotechnology-based, catalyst-mediated series of chemical reactions to turn carbon dioxide (C (a greenhouse gas) into a usable fuel, scientists at the Department of Energy’s Oak Ridge National Laboratory instead discover a single-step process using the surface area of tiny spikes of copper and carbon as a catalyst to turn carbon dioxide into ethanol (C C O. The reaction may serve as a method to alleviate possible climate change by both decreasing C in the atmosphere and by using the ethanol as an additive to fuels to increase efficiency and thereby decrease consumption.

Researchers in Iceland report on CarbFix, in the journal "Science", that carbon dioxide emissions can be pumped into the earth and changed chemically to stone  — significantly faster than expected.

An analysis of data detected by the Lunar Reconnaissance Orbiter of the LCROSS impact last October finds the presence of carbon monoxide in Cabeus Crater in higher concentrations than the approximately 155 kg of water ice and water vapour, more than initially estimated, in addition to two hydroxyl flavours and smaller quantities of hydrogen sulfide, carbon dioxide, sulfur dioxide, methane, formaldehyde, mercury, magnesium, calcium, sodium, hydrogen gas, and possibly ammonia, ethylene and silver.
